Functional shoe

Abstract

Disclosed is a functional shoe, comprising a foot arch support, wherein said foot arch support includes a support body accommodated and fixed in a shoe body, a slider tightened to the support body by a screw, and a contact member which is coupled to the top of the slider and projects toward the inside of the shoe to contact the arch of the foot. The slider moves in the upward and downward directions by means of the rotation of the contact member.

1 . A shoe having functionality and provided with an arch support, the arch support comprising:
 a supporting member inserted and fixed at a position corresponding to a foot arch in a body of the shoe;   a slider screw-coupled to the supporting member, to be raised and lowered through rotation thereof; and   a contacting member coupled at a top of the slider to project inward in the shoe and contact the foot arch.   
     
     
         2 . The shoe of  claim 1 , wherein the supporting member is cylindrical and defines screw threads in an inside thereof, and the slider is inserted inside the supporting member. 
     
     
         3 . The shoe of  claim 1 , wherein the contacting member is formed of a rubber material in a semispherical shape. 
     
     
         4 . The shoe of  claim 1 , wherein the contacting member is separably coupled to the slider, and the rotation of the slider separate from the contacting member raises and lowers the slider. 
     
     
         5 . The shoe of  claim 4 , wherein the contacting member is formed in a shape corresponding to the foot arch. 
     
     
         6 . The shoe of  claim 1 , wherein the arch support further comprises a pair of supporting rods that projects from a surface of the contacting member that couples to the slider, and inserts in the shoe body. 
     
     
         7 . A shoe having functionality and provided with an arch support, the arch support comprising:
 a cylindrical housing inserted and fixed at a position corresponding to a foot arch in a body of the shoe;   a bolt fixed in the housing and including a head at a bottom thereof;   a cylindrical slider inserted in the housing to be slidable and raised and lowered, and having the bolt screw-coupled therein; and   a contacting member coupled to a top of the slider to project inward in the shoe and contact the foot arch, wherein   the slider is raised and lowered by rotating the head of the bolt from outside through a floor of the shoe body.   
     
     
         8 . The shoe of  claim 7 , wherein the arch support further comprises a pair of supporting rods that projects from a surface of the contacting member that couples to the slider, and inserts in the shoe body. 
     
     
         9 . A shoe having functionality and provided with an arch support, the arch support comprising:
 a cylindrical housing inserted and fixed at a position corresponding to a foot arch in a body of the shoe;   a cylindrical slider inserted in the housing to be slidable and raised and lowered;   a height-adjusting tab inserted and screw-coupled in the slider; and   a contacting member coupled to a top of the slider to project inward in the shoe and contact the foot arch, wherein   the slider is raised and lowered by adjusting a length by which the height-adjusting tab projects from the slider.   
     
     
         10 . The shoe of  claim 9 , wherein the arch support further comprises a pair of supporting rods that projects from a surface of the contacting member that couples to the slider, and inserts in the shoe body. 
     
     
         11 . A shoe having functionality and provided with an arch support, the arch support comprising:
 a contacting member projecting inward in the shoe to contact a foot arch;   a cylindrical slider coupled to a reverse surface of the contacting member; and   a height-adjusting tab inserted and screw-coupled in the slider, wherein   a body of the shoe defines a receptacle for receiving the arch support, and a supporting niche defined into and around a sidewall of the receptacle at a mouth of the receptacle, a perimeter of the contacting member being forcibly inserted in the supporting niche, and the arch support is adjusted in height by adjusting a length by which the height-adjusting tab projects from the slider.
